FRANK MOSES, OF TORONTO, CANADA.

HOT-AIR FURNACE AND COOKING-STOVE.

SPECIFICATION forming part of Letters Patent No. 467,755, dated January 26, 1892. Application filed March 31, 1891. Serial No. 387,165. (No model.)

ToaZZ whom it may concern.-

Be it known that I, FRANK MOSES, of the city of Toronto, in the county of York, in the- Province of Ontario, Canada, have invented a certain new and useful Combined IIot-Air Furnace and Cooking-Stove, of which the following is a specification.

The object of the invention is to adapt an ordinary hot-air furnace so that it may be utilized for a cooking-stove without in any way interfering with its usefulness as a hotair furnace; and it consists, essentially, of a series of pot-holes arranged around the furnace and connected to its firepot, an oven located above the fire-pot, and a series of fiues and pipes connecting the interior of the firepot with the interiorof the chamber surrounding the oven in such a manner as to convey the smoke and heated gases from the fire-pot past each pot-hole therein to the chamber surrounding the oven, substantially as hereinafter more particularly explained and then definitely claimed.

Figure l is a perspective View of my improved device With parts broken away. Fig. 2 is a sectional elevation of the apparatus, showing by arrows the course of the smoke and products of combustion. Fig. 3 is aplan of the pot-hole and its flue.

In the drawings I show two pot-holesA, but I do not confine myself to any particular numher, as more or less may be used according to the taste of the manufacturer; but I may say that I prefer two pot-holes on each side of the furnace. These pot-holes communicate with the fire-pot of the furnace, and each is surrounded by a flue B from which the pipes B extend. A hole protected by a damper O is made in the wall of the flue B, through which hole the smoke and heated gases must pass before they reach the pipes B, which pipes lead to the chamber 0, surrounding the oven D. The base E of the chamber 0 is immedi- \Vhen this damper F is opened, the smoke and heated gases will pass directly into the chamber O, and thence out through the smoke-pipe G. hen this damper F is closed, the smoke and'heated gases will be directed toward the pot-holes A, passing through the hole in the wall of the flue B, and thence up through the pipe B into the chamher 0. In this way I utilize the indirect draft of the furnace for the purpose of cooking on the pot-holes A and in the chamber D. As the pipes B are arranged in the hot-air space II, the smoke and heated gases passing through them are utilized to the fullest extent for the purpose of heating the air passing through the said air-space H, which hot air is conveyed through the pipes I in the ordinary manner.

From this description it will be seen that I utilize the heat from the fire-pot of an ordinary furnace for cooking purpose without in any way detracting from the usefulness of the hot-air furnace for its ordinary purpose.

What I claim as my invention is 1. The chamber O, located above the firepot of an ordinary hot-air furnace and surrounding an oven D, in combination with a series of pipes B, arranged within the hot-air space H and connecting the interior of the fire-pot with the interior of the chamber 0, and an adjustable damper F, substantially as and for the purpose specified.

2. A hot-air furnace having one or more pot-holes A extending from the side of its fire-pot, a series of pipes B, arranged to connect the interior of the fire-pot with the interior of the chamber O, located above the said fire-pot, in combination with an oven D, located within the chamber 0, and an adj ustable damper arranged over a hole in the base of the chamber 0, substantially as and for the purpose specified.
